The Hutchinson Cobra 29er mountain bike tires are tough enough for Team Orbea and riding in the Basque mountains, so you be darned sure they're ready for whatever ride you're taking them on. The Cobra's were designed by Julien Absalon and Team Orbea to create a durable, resilient tire that would perform excellently in the dry conditions found the Basque country. The high density knob pattern, aggressive shoulder knobs and 33 TPI casing help you get plenty of traction when the trail turns dry and dusty.
